尽管我的项目是 .Net 4.5，但我遇到了完全相同的问题。我按照 Upgrading an ASP.NET MVC 3 Project to ASP.NET MVC 4 的第 7 步解决了它

复制到这里如下:

7.如果项目引用了使用以前版本的ASP.NET MVC编译的任何第三方库，请打开根Web.config文件并在配置部分下添加以下三个bindingRedirect元素:

 <configuration>
  <!--... elements deleted for clarity ...-->

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Helpers" 
             publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" 
             publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="4.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages" 
             publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>
